State-owned airport operator and air navigation service provider Avinor will carry out Norway’s most extensive airspace reorganization to date on November 13. The company advised that flights into Norway will be delayed when it makes the changes.

The changes involve air traffic management routines and flight procedures, and are centered in southwest Norway. They will “influence” 16 airports overall, including those in Stavanger, Bergen and Trondheim, Avinor said.

The company provided a detailed description of the changes, which include merging some terminal maneuvering areas, introducing new area control center sectors and applying “dynamic sectorization,” in which area and approach sectors will be opened and closed according to traffic demand. Segregated area navigation (Rnav) routes will facilitate continuous climbs and descents. The airspace reorganization aims to accommodate future air traffic growth while improving efficiency and reducing emissions.

Once it makes the airspace changes, Avinor will reduce the number of hourly arrivals at the largest airports to ensure the system is working properly. “Restrictions will be highest immediately after the implementation, with the largest delays expect­ed in the morning hours of the 13^th,” the company said. “Restrictions will gradually be lifted, until normal operations are allowed. Avinor is working closely with the airlines to reduce consequences as much as possi­ble for travelers.”

Avinor said changes will affect the following airports: Bergen/Flesland, Florø, Førde/Bringeland, Haugesund/Karmøy, Kristiansand/Kjevik, Kris­tiansund/Kvernberget, Molde/Årø, Røros, Sandane/Anda, Sogndal, Stord/Sørstokken, Stavanger/ Sola, Trondheim/Værnes, Ørland, Ørsta-Volda/Hovden and Ålesund/Vigra.
